Detailed Description

System to help automate game object construction, destruction, and serialization.

ReplicaManager3 tracks your game objects and automates the networking for replicating them across the network
As objects are created, destroyed, or serialized differently, those changes are pushed out to other systems.
To use:

Derive from Connection_RM3 and implement Connection_RM3::AllocReplica(). This is a factory function where given a user-supplied identifier for a class (such as name) return an instance of that class. Should be able to return any networked object in your game.
Derive from ReplicaManager3 and implement AllocConnection() and DeallocConnection() to return the class you created in step 1.
Derive your networked game objects from Replica3. All pure virtuals have to be implemented, however defaults are provided for Replica3::QueryConstruction(), Replica3::QueryRemoteConstruction(), and Replica3::QuerySerialization() depending on your network architecture.
When a new game object is created on the local system, pass it to ReplicaManager3::Reference().
When a game object is destroyed on the local system, and you want other systems to know about it, call Replica3::BroadcastDestruction()

At this point, all new connections will automatically download, get construction messages, get destruction messages, and update serialization automatically.

Member Function Documentation

virtual Connection_RM3* RakNet::ReplicaManager3::AllocConnection	(	const SystemAddress &	systemAddress,
		RakNetGUID	rakNetGUID
	)			const `[pure virtual]`

Implement to return a game specific derivation of Connection_RM3.

The connection object represents a remote system connected to you that is using the ReplicaManager3 system.
It has functions to perform operations per-connection.
AllocConnection() and DeallocConnection() are factory functions to create and destroy instances of the connection object.
It is used if autoCreate is true via SetAutoManageConnections() (true by default). Otherwise, the function is not called, and you will have to call PushConnection() manually

Note:: If you do not want a new network connection to immediately download game objects, SetAutoManageConnections() and PushConnection() are how you do this.

See also:: SetAutoManageConnections()

Parameters:

`[in]`	systemAddress	Address of the system you are adding
`[in]`	rakNetGUID	GUID of the system you are adding. See Packet::rakNetGUID or RakPeerInterface::GetGUIDFromSystemAddress()

Returns:: The new connection instance.

void RakNet::ReplicaManager3::BroadcastDestructionList	(	DataStructures::List< Replica3 * > &	replicaListSource,
		const SystemAddress &	exclusionAddress
	)

Send a network command to destroy one or more Replica3 instances Usually you won't need this, but use Replica3::BroadcastDestruction() instead. The objects are unaffected locally

Parameters:

`[in]`	replicaList	List of Replica3 objects to tell other systems to destroy.
`[in]`	exclusionAddress	Which system to not send to. UNASSIGNED_SYSTEM_ADDRESS to send to all.

virtual void RakNet::ReplicaManager3::DeallocConnection ( Connection_RM3 * connection ) const [pure virtual]

Implement to destroy a class instanced returned by AllocConnection().

Most likely just implement as {delete connection;}
It is used if autoDestroy is true via SetAutoManageConnections() (true by default). Otherwise, the function is not called and you would then be responsible for deleting your own connection objects.

Parameters:

[in] connection The pointer instance to delete

void RakNet::ReplicaManager3::Dereference ( RakNet::Replica3 * replica3 )

Removes a replicated object from the system.

The object is not deallocated, it is up to the caller to do so.
This is called automatically from the destructor of Replica3, so you don't need to call it manually unless you want to stop tracking an object before it is destroyed.

Parameters:

[in] replica3 The object to stop tracking

void RakNet::ReplicaManager3::DereferenceList ( DataStructures::List< Replica3 * > & replicaListIn )

Removes multiple replicated objects from the system.

Same as Dereference(), but for a list of objects.
Useful with the lists returned by GetReplicasCreatedByGuid(), GetReplicasCreatedByMe(), or GetReferencedReplicaList().

Parameters:

[in] replicaListIn List of objects

Connection_RM3* RakNet::ReplicaManager3::GetConnectionAtIndex ( unsigned index ) const

Returns a connection pointer previously added with PushConnection().

Parameters:

[in] index An index, from 0 to GetConnectionCount()-1.

Returns:: A Connection_RM3 pointer

Connection_RM3* RakNet::ReplicaManager3::GetConnectionByGUID ( RakNetGUID guid ) const

Returns a connection pointer previously added with PushConnection.().

Parameters:

[in] guid The guid of the connection to return

Returns:: A Connection_RM3 pointer, or 0 if not found

Connection_RM3* RakNet::ReplicaManager3::GetConnectionBySystemAddress ( const SystemAddress & sa ) const

Returns a connection pointer previously added with PushConnection().

Parameters:

[in] sa The system address of the connection to return

Returns:: A Connection_RM3 pointer, or 0 if not found

unsigned int RakNet::ReplicaManager3::GetConnectionCount ( void ) const

Returns the number of connections.

Returns the number of connections added with ReplicaManager3::PushConnection(), minus the number removed with ReplicaManager3::PopConnection()

Returns:: The number of registered connections

void RakNet::ReplicaManager3::GetConnectionsThatHaveReplicaConstructed	(	Replica3 *	replica,
		DataStructures::List< Connection_RM3 * > &	connectionsThatHaveConstructedThisReplica
	)

Return the connections that we think have an instance of the specified Replica3 instance.

This can be wrong, for example if that system locally deleted the outside the scope of ReplicaManager3, if QueryRemoteConstruction() returned false, or if DeserializeConstruction() returned false.

Parameters:

`[in]`	replica	The replica to check against.
`[out]`	connectionsThatHaveConstructedThisReplica	Populated with connection instances that we believe have replica allocated

void RakNet::ReplicaManager3::GetReferencedReplicaList ( DataStructures::List< Replica3 * > & replicaListOut )

Returns the entire list of Replicas that we know about.

This is all Replica3 instances passed to Reference, as well as instances we downloaded and created via Connection_RM3::AllocReference()

Parameters:

[out] List of Replica3 instances to be returned

Replica3* RakNet::ReplicaManager3::GetReplicaAtIndex ( unsigned index )

Returns a replica by index.

Returns one of the items in the list that would be returned by GetReferencedReplicaList()

Parameters:

[in] index An index, from 0 to GetReplicaCount()-1.

Returns:: A Replica3 instance

unsigned RakNet::ReplicaManager3::GetReplicaCount ( void ) const

Returns the number of replicas known about.

Returns the size of the list that would be returned by GetReferencedReplicaList()

Returns:: How many replica objects are in the list of replica objects

void RakNet::ReplicaManager3::GetReplicasCreatedByGuid	(	RakNetGUID	guid,
		DataStructures::List< Replica3 * > &	replicaListOut
	)

Returns all objects originally created by a particular system.

Originally created is defined as the value of Replica3::creatingSystemGUID, which is automatically assigned in ReplicaManager3::Reference().
You do not have to be directly connected to that system to get the objects originally created by that system.

Parameters:

`[in]`	guid	GUID of the system we are referring to. Originally passed as the guid parameter to ReplicaManager3::AllocConnection()
`[out]`	List	of Replica3 instances to be returned

void RakNet::ReplicaManager3::GetReplicasCreatedByMe ( DataStructures::List< Replica3 * > & replicaListOut )

Returns all objects originally created by your system.

Calls GetReplicasCreatedByGuid() for your own system guid.

Parameters:

[out] List of Replica3 instances to be returned

unsigned char RakNet::ReplicaManager3::GetWorldID ( void ) const

Returns:: Whatever was passed to SetWorldID(), or 0 if it was never called.

virtual void RakNet::ReplicaManager3::OnClosedConnection	(	const SystemAddress &	systemAddress,
		RakNetGUID	rakNetGUID,
		PI2_LostConnectionReason	lostConnectionReason
	)			`[protected, virtual]`

Called when a connection is dropped because the user called RakPeer::CloseConnection() for a particular system

Parameters:

`[in]`	systemAddress	The system whose connection was closed
`[in]`	rakNetGuid	The guid of the specified system
`[in]`	lostConnectionReason	How the connection was closed: manually, connection lost, or notification of disconnection

Reimplemented from RakNet::PluginInterface2.

virtual void RakNet::ReplicaManager3::OnNewConnection	(	const SystemAddress &	systemAddress,
		RakNetGUID	rakNetGUID,
		bool	isIncoming
	)			`[protected, virtual]`

Called when we got a new connection

Parameters:

`[in]`	systemAddress	Address of the new connection
`[in]`	rakNetGuid	The guid of the specified system
`[in]`	isIncoming	If true, this is ID_NEW_INCOMING_CONNECTION, or the equivalent

Reimplemented from RakNet::PluginInterface2.

virtual PluginReceiveResult RakNet::ReplicaManager3::OnReceive ( Packet * packet ) [protected, virtual]

OnReceive is called for every packet.

Parameters:

[in] packet the packet that is being returned to the user

Returns:: True to allow the game and other plugins to get this message, false to absorb it

Reimplemented from RakNet::PluginInterface2.

RakNet::Connection_RM3* RakNet::ReplicaManager3::PopConnection ( RakNetGUID guid )

Stop tracking a connection.

On call, for each replica returned by GetReplicasCreatedByGuid(), QueryActionOnPopConnection() will be called. Depending on the return value, this may delete the corresponding replica.
If autoDestroy is true in the call to SetAutoManageConnections() (true by default) then this is called automatically when the connection is lost. In that case, the returned connection instance is deleted.

Parameters:

[in] guid of the connection to get. Passed to ReplicaManager3::AllocConnection() originally.

bool RakNet::ReplicaManager3::PushConnection ( RakNet::Connection_RM3 * newConnection )

Track a new Connection_RM3 instance.

If autoCreate is false for SetAutoManageConnections(), then you need this function to add new instances of Connection_RM3 yourself.
You don't need to track this pointer yourself, you can get it with GetConnectionAtIndex(), GetConnectionByGUID(), or GetConnectionBySystemAddress().

Parameters:

[in] newConnection The new connection instance to track.

void RakNet::ReplicaManager3::Reference ( RakNet::Replica3 * replica3 )

Adds a replicated object to the system.

Anytime you create a new object that derives from Replica3, and you want ReplicaManager3 to use it, pass it to Reference().
Remote systems already connected will potentially download this object the next time ReplicaManager3::Update() is called, which happens every time you call RakPeerInterface::Receive().
You can also call ReplicaManager3::Update() manually to send referenced objects right away

Parameters:

[in] replica3 The object to start tracking

void RakNet::ReplicaManager3::SetAutoManageConnections	(	bool	autoCreate,
		bool	autoDestroy
	)

Enable or disable automatically assigning connections to new instances of Connection_RM3.

ReplicaManager3 can automatically create and/or destroy Connection_RM3 as systems connect or disconnect from RakPeerInterface.
By default this is on, to make the system easier to learn and setup.
If you don't want all connections to take part in the game, or you want to delay when a connection downloads the game, set autoCreate to false.
If you want to delay deleting a connection that has dropped, set autoDestroy to false. If you do this, then you must call PopConnection() to remove that connection from being internally tracked. You'll also have to delete the connection instance on your own.

Parameters:

`[in]`	autoCreate	Automatically call ReplicaManager3::AllocConnection() for each new connection. Defaults to true.
`[in]`	autoDestroy	Automatically call ReplicaManager3::DeallocConnection() for each dropped connection. Defaults to true.

void RakNet::ReplicaManager3::SetAutoSerializeInterval ( RakNet::Time intervalMS )

Every intervalMS milliseconds, Connection_RM3::OnAutoserializeInterval() will be called.
Defaults to 30.
Pass with <0 to disable. Pass 0 to Serialize() every time RakPeer::Recieve() is called
If you want to control the update interval with more granularity, use the return values from Replica3::Serialize().

Parameters:

[in] intervalMS How frequently to autoserialize all objects. This controls the maximum number of game object updates per second.

void RakNet::ReplicaManager3::SetDefaultOrderingChannel ( char def )

Parameters:

[in] Default ordering channel to use for object creation, destruction, and serializations

void RakNet::ReplicaManager3::SetDefaultPacketPriority ( PacketPriority def )

Parameters:

[in] Default packet priority to use for object creation, destruction, and serializations

void RakNet::ReplicaManager3::SetDefaultPacketReliability ( PacketReliability def )

Parameters:

[in] Default packet reliability to use for object creation, destruction, and serializations

void RakNet::ReplicaManager3::SetNetworkIDManager ( NetworkIDManager * _networkIDManager )

Sets the networkIDManager instance that this plugin relys upon.
Uses whatever instance is attached to RakPeerInterface if unset.
To support multiple worlds, you should set it to a different manager for each instance of the plugin

Parameters:

[in] _networkIDManager The externally allocated NetworkIDManager instance for this plugin to use.

void RakNet::ReplicaManager3::SetWorldID ( unsigned char id )

Defines the unique instance of ReplicaManager3 if multiple instances are on the same instance of RakPeerInterface.

ReplicaManager3 supports multiple instances of itself attached to the same instance of rakPeer, in case your game has multiple worlds.
Call SetWorldID with a different number for each instance.
The default worldID is 0.
To use multiple worlds, you will also need to call ReplicaManager3::SetNetworkIDManager() to have a different NetworkIDManager instance per world
